The ward was founded on March 15, 1947, merging the old wards ofŌmori andKamata. The ward's name originates from the combination of letters of the two merging wards,Ōmori (大森) and Kamata (蒲田), combined intoŌta (大田). The ward was previously second behind Setagaya in terms of being the largest special ward in Tokyo by area, but due toland reclamation in theTokyo Bay for the expansion of the Haneda Airport (羽田空港), Ōta overtook Setagaya for first place.
Haneda Airport, now one of the two main domestic and international airports serving theGreater Tokyo Area (the other one beingNarita Airport inNarita, Chiba) was first established as Haneda Airfield in 1931 in the town ofHaneda, Ebara District ofTokyo Prefecture. FollowingJapan's surrender in 1945, the airfield was turned into the Haneda Army Air Base under the control of theUnited States Army. In the same year,Allied occupational authorities ordered the expansion of the airport, evicting people from the surroundings on 48 hours' notice. With the end of the occupation, the Americans returned part of the facility to Japanese control in 1952, completing the return in 1958.
